Every RVer knows the frustration of a trailer creeping during loading or shifting overnight. Cheap plastic chocks crack under weight, while metal ones damage tires. Lippert's solution? A vulcanized rubber chock engineered to withstand 10,000+ lbs of pressure without slipping—even on steep inclines or wet surfaces.
Features
- Military-grade traction: Diamond-tread pattern grips pavement, gravel, or dirt (tested to 45° slope)
- Ergonomic handling: Molded 2" deep handle slots for single-handed placement
- All-weather durability: -40°F to 200°F operational range resists cracking
- Universal fit: 8" length accommodates tires from 12" to 22.5" diameter
- Weighted stability: 3.2-lb dense rubber construction prevents blow-away
- Lippert engineered: Meets RVIA/ABYC safety standards for trailer equipment
Unlike flimsy alternatives, this chock's vulcanized rubber compound compresses slightly under load to create a vacuum seal against the tire. The result? Zero rollback even when disconnecting heavy fifth wheels. RVers report using the same pair for 7+ seasons without degradation.
Designed specifically for RVs, the 6" width provides full tire coverage while the 4" height clears most leveling jacks. The tapered front edge slides effortlessly under low-clearance trailers—no more wrestling with misaligned chocks.

- Will this work on gravel or dirt? Yes—the diamond-tread pattern grips loose surfaces better than smooth chocks. Many customers use them at campsites with uneven terrain.
- How many chocks do i need per trailer? Always use two chocks (one per tire) on the downhill side when parked on slopes. For flat surfaces, one per wheel is sufficient.
- Will this melt on hot asphalt? No. The special rubber compound withstands temperatures up to 200°F without deforming.
- What's the difference between this and cheaper chocks? Lippert's vulcanized rubber won't crack like plastic or damage tires like metal. The silica additive prevents dry rot for 5x longer lifespan.
